Seeking Laptop Donation for a Good Cause?

Johannes asks: "I'm working in a home for mentally heavily disabled children and I'm the computertechnician here. We are in need of a old notebook (486, min 120MB HDD, min. 4 MB Ram, B/W-Screen) to keep all the information of our children. After my request to IBM, Sony, Siemens I always received the same answer: 'Our budget doesn't allow us this year to help you'. Are these companies so poor that they can't not even find a notebook with our needed specifications? Anyway, until today we weren't successful, so I would like to ask all readers from Slashdot: does someone out in the big world have notebook, which he doesn't need anymore? Our home is situated in South Africa near Pretoria and we are fully dependant on donations." The standard answer IBM, Sony and the others provided seems like a dodge to me. Does anyone out there have a laptop to donate for a good cause?
